I'm assuming you mean the total of both is 84.  So 9 am has 38 students and 11 am has 46 students  I basically just divided total of 84 by 2, added half the difference (4) to the 11 am and subtracted half the difference (4) from the 9am

Write each as the sum of two terms in the form t_n,r. t_5,3 , t_11,2 , t_15,13
Anarel [89]

The sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.

<h3>What is the sum about?</h3>

The sum of two numbers is one that tells you to find the sum of two or more numbers, and as such, you have to add the numbers altogether.

t₅, ₃ =  5 + 3

= 8

t₁₁, ₂ = 11 + 2

= 13

t₁₅,₁₃ =  15 + 13

= 28.

Hence the correct sum of two terms are:

  • t₅, ₃ = 8
  • t₁₁, ₂ = 13
  • t₁₅,₁₃ = 28.

1. Given that 4x²- 16x + 15 = a(x-p)²+ q for all values of x.
FinnZ [79.3K]

Answer:

a = 4, p = 2, q = - 1

Step-by-step explanation:

Expand the right side of the identity, then compare the coefficients of like terms with those on the left side.

a(x - p)² + q ← expand (x - p)² using FOIL

= a(x² - 2px + p²) + q  ← distribute parenthesis

= ax² - 2apx + ap² + q

Compare coefficients of x² term

a = 4

Compare coefficients of x- term

- 2ap = - 16, that is

- 2(4)p = - 16

- 8p = - 16 ( divide both sides by - 8 )

p = 2

Compare constant terms

ap² + q = 15 , that is

4(2)² + q = 15

16 + q = 15 ( subtract 16 from both sides )

q = - 1

Thus a = 4, p = 2, q = - 1

Please help PLEASE I really need help with this question
Semenov [28]

Answer:

f(-4) = 9

Step-by-step explanation:

To find which expression to use, see which one x = -4 fits in. That is <em>x² - 5</em>, since -4 < 3.

Then, plug in the number: (-4)² - 5

Square: 16 - 5

Subtract: 9

f(-4) = 9
